1. If GM builds the best 6th Gen they can based on GM powertrain and chassis technology they need not pay any attention to what Ford or any other company does. GM should lead and not follow.

2. The Z/28 does not need to turn a profit. It needs to move iron and not lose money. If the Z/28 can keep the utilization above the magical BE in the final year of production the line makes money even if the car doesn't.
